Orders Extensibility Samples
The Commerce Server Core Systems SDK includes two samples that illustrate how to extend the Orders System:
Extending the LineItem class.
Implementing virtual gift certificates.
You can find the source code for these samples and the files that support them, such as the Web.config file, in the %COMMERCE_SERVER_ROOT%/SDK/Samples/OrdersExtensibility folder. The Readme.txt file in that directory contains instructions for running the samples. Both samples are implemented within a single application. However, the topics in this section describe the samples independently.
